Definitions

  • the present invention relates to an electromagnetic Switchgear with at least one drive coil, when applied with a pull-in current into a contact carrier Actuating direction shifts and so at least one Main contact actuated, the contact carrier also one Auxiliary switch operated, the auxiliary switch by the Moving the contact carrier from a spring-loaded rest position released in a sprung actuation position and the contact carrier via a lever on the auxiliary switch acts.
  • Such a switching device is such. B. from EP 0 511 042 A1 known.
  • Electromagnetic switching devices in particular contactors, have often auxiliary switches on, together with the main contact or the main contacts. This occurs Problem on that the auxiliary switch due to the high speed the contact carrier of a large mechanical Exposed to stress and therefore designed very stable need to be, although this is intended for carrying out them electrical function is not required. The Auxiliary switches are therefore comparatively expensive.
  • the object of the present invention is a to design electromagnetic switching device such that the auxiliary switch for switching the coil current no longer the mechanical occurring when the contact carrier is actuated Is exposed to stress.
  • the task is - starting from EP 0 511 042 A1 - thereby solved that the lever has a translation that is greater than one, in particular is at least two, and that the operation of the auxiliary switch switches the Loading the drive coil with a holding current, which is considerably smaller than the drive current.
  • the lever can be used, for example, as an angle lever or as a bar lever be trained.
  • the lever can also be used as an or two-sided lever be formed.
  • the auxiliary switch can, for example, with one of the drive coil upstream current control connected to this from supplying the starting current to supplying a considerably smaller one Switch current.
  • the switching device has no control electronics, it can easily switch from pull-in to holding current can be reached if the auxiliary switch is in the spring loaded Closed position and in the extended actuation position is open, the drive coil has two partial windings and the auxiliary switch with one of the partial windings is connected in series.
  • an electromagnetic switching device 1 has a drive coil 2.
  • the drive coil 2 is acted upon by a starting current I A. This then shifts a contact carrier 3 in an actuation direction x. As a result, a main contact 4 and an auxiliary switch 5 are actuated.
  • the auxiliary switch 5 is connected to a current control 6, which is arranged upstream of the drive coil 2. Due to the actuation of the auxiliary switch 5, the current control 6 is switched over so that it only applies a holding current I H to the drive coil 2 which is considerably smaller than the starting current I A.
  • the contact carrier 3 acts via a Lever 7 on the auxiliary switch 5.
  • the lever 7 is according to the 2 and 3 designed as a two-sided lever 7. He could but also be designed as a one-sided lever.
  • the lever 7 is designed as an angle lever 7, according to FIG. 3 as a beam lever 7.
  • the auxiliary switch 5 has a switch spring according to FIGS 2 and 3 8, which is an actuator 9 of the auxiliary switch 5 presses against the lever 7.
  • the lever 7 also acts a return spring 10.
  • the return spring 10 via the lever 7 is force exerted on the actuating element 9 larger than that of the switch spring 8 on the actuator 9 force exerted. If the contact carrier is not moved 3 the actuating element 9 therefore remains in a rest position, in which the switch spring 8 is compressed. By moving the contact carrier 3 becomes the return spring 10 but forcibly compressed and the lever 7 from the actuator 9 solved. The actuator 9 is thus released so that the auxiliary switch 5 in an operating position can pass into the switch spring 8 rebounded is.
  • the translation of the lever 7, i.e. the ratio of its lever arms, is preferably greater than one, in particular at least two. Because it is despite a late actuation of the auxiliary switch 5, that is, an operation of the auxiliary switch 5 only shortly before the main contact 4 is actuated, possible to ensure a large opening path of the auxiliary switch 5. There is also an exact switching time of the auxiliary switch 5 guaranteed.
  • the switching device 1 has no control electronics in the form of a current control 6. Instead, the drive coil 2 has two partial windings 2 ', 2 ". By means of one partial winding 2', the contact carrier 3 is moved in the actuation direction x when the starting current I A is applied . The other partial winding 2 'is acted upon by the holding current I H
  • the auxiliary switch 5 is designed as a normally open contact 5. It is therefore closed in the sprung-in rest position and opened in the sprung-out actuation position. It is connected in series with the one partial winding 2 ' Without control electronics, a simple switchover from the pull-in current I A to the holding current I H is guaranteed.
